Hamann offers cosmetic changes such as low profile spoilers, bodykits, carbon fiber splitters, and multi-piece alloy wheels. Other upgrades include racing LSDs, open racing exhaust systems, twelve-piston disc brakes, and engine remapping. The company orders crate engines from the dealership and then redesigns them.The company designs and builds upon numerous parts of the original car, such as tuning the car's engine, lowering the car, making a new body with more features, and installing racing tires.

First car from the Hamann Motorsport was BMW M3 (E30), each producing 348 PS (256 kW) from a 2.3L R4 engine (with Turbocharger). The car accelerate from 0-60 mph in 5.1 seconds and reach top speed of 170 mph (273 km/h).

Hamann Motorsports designed a variety of cars, for instance, the Lamborghini Murciélago LP640. Hamann built the engine from scratch to enhance the horsepower to reach 690HP by modifying the engine management system and installing a custom made exhaust system. For the exterior Hamann did not change much, they only installed the matte black wheels.
